The critical measurement in addition to anchor height (overall length of everything) is the stock length, the width of the outer rods. They snap into clips on the rim of the locker opening, That said, a lot of danforth anchors will 'fit' but you may need to shorten (hacksaw) the rod ends,
In addition the bigger the anchor, the less rode that can be stored.
For typical weather conditions and sandy sea beds, a 5 pound danforth is sufficient.
You'll want to measure those things that Seasick mentioned. Different anchor manufacturers will different measurements. So you need thos measurents and then compare to the anchors you are considering. It's not a "black and white" thing - there are many shades of grey here.
